MODULATION IS REQUIRED FORSelect one:a. REDUCTION IN THE COMPLEXITY OF CIRCUITRYb. ALL OF THE ABOVEc. REDUCTION OF ANTENNA HEIGHTd. REDUCING NOISE WHILE TRANSMISSIONe. MULTIPLEXING THE SIGNALS

Modulation is required for:

c. Reduction of antenna height: Modulation allows us to transmit signals over long distances. Without modulation, we would need an antenna as tall as the wavelength of the signal, which is impractical for low-frequency signals.

d. Reducing noise while transmission: Modulation helps in reducing the noise interference during the transmission of signals. It improves the quality of the received signal.

e. Multiplexing the signals: Modulation is used in the process of multiplexing where multiple signals are combined into one signal for transmission. It helps in efficient use of bandwidth.

So, the correct answer is b. All of
